RAZOR.

Specification of Letters Patent.

Patented Nov. 30, 192 0.

Application filed December 1, 1919. Serial No. 341,612.

T 0 all w item it may concern:

Be it known that I, ANDREW MoANULrr, a subject of the King of GreatBritain, a resident of the city of Ottowa, Province of Ontario, Dominionof Canada, have in vented certain new and useful Improvements in Razors,of which the following is a specification.

This invention relates to improvements in razors, and the objects of theinvention are to permit of an ordinary blade razor being utilized eitheras a straight blade or as a safety razor, to provide means whereby thesafety device may be concealed within the handle of the razor when notin use, and to facilitate attaching and detaching the safety device tothe razor blade, with a minimum of time and efiort.

Further objects are to permit of the safety device being adjustedrelatively to the razor blade so that it will compensate for any wear ofthe razor blade, that is to say, the safety device will be positionedrelatively to the edge of the blade in the position best adapted toallow the razor and safety device to perform the functions required ofthem, to give adequate clearance between the safety device and the bladewhen the former is not in use, and generally to adapt the razor tobetter perform the functions required of it.

With the above and other objects in view,

- the invention consists essentially of the improved constructionparticularly described and set forth in the following specification andaccompanying drawings forming part of the same. v

In the drawings:

Figure 1 is a side elevation of a straight blade razor, showing theimproved safety device, part of the handle being broken away to show themeans for retaining the safety device within the handle-when not in use.

Fig: 2 is a side elevation of an alternative form of'the safety device.

connected. I

Fig. 4 is a side elevation of the safety de- 1 viceshown in Fig. 3 withthe parts connected. I

Fig. 5 is a longitudinal sectlon of the straight bladeshowing the safetydevice in engagement therewith.

- Fig. 6 is a plan view of the straight blade razor showing the safetydevice located within the handle and retained in position therein.

Fig. 7 is a side elevation of a straight blade showing an alternativeform of the safety dev1ce and means for securing the same disengagedfrom the blade.

Fig. 8 is a side elevation of that alternative form of the safety deviceshown in Fig. 7 showing it in engagement with the blade.

Like characters of reference refer to like parts in the several figures.

In shaving with a straight blade razor, many people use both the rightand left hand, and under such circumstances the safety attachment wouldrequire to be duplicated, that is to say, one located on each side ofthe blade. I n

For descriptive purposes, however, I have only illustrated one safetydevice to the blade, the other being leftout as it would only add to thecomplexity of the drawings.

In the embodiment of my invention illustrated, A represents an ordinarystraight blade razor provided with a handle 10 to which the blade ishinged by a pin 11 the blade being provided on the shank with a lateralprojection 12 having under out edges. I t g .The two portions of thehandle 10 are spaced by distance piece 13 located at the end remote fromthe hinge pin 11 of the blade, and this distance piece has an undercutedge 14 forming a lip 15, which projects inwardly and longitudinally ofthe handle.

Intermediate of the ends of the handle a second distance piece 16 isprovided which also acts as a guide to facilitate securing the safety.device B to the blade A, in a manner to be made clear hereafter.

The safety device B has a serration or tooth blade portion 17 and theshank 18 arranged in parallelism with the hand and connected by anoffset integral portion 19.

The safety device B is pivoted to the.

hinge pin 11, but is capable of longitudinal movement to a limitedextent, and thatend of the shank remote from the hinge pin 11 isprovided with a keyhole slot 20 adjacent to whicha projecting pin 21 islocated to form a finger grip. The end of the blade of the safety deviceB remote from the hinge pin 11. is provided with a hooked end 22.

To hold the safety device B in spring engagement with the blade of therazor, there is provided a longitudinally extending and slightly offsetspringportions 23 formed integral with the shank 18, the portions beingmade of the same material the safety device B.

hen this form of my invention is in use, it will assume the positionshown in Fig. 6 when closed, the safety device B lying within the twoside members of the handle 10, and the device B will have been movedlongitudinally toward the distance piece so that the hooked end 22 willslightly project below the lip 15 of the said distance piece thussecuring safety device B within the side member of the handle 10 andpermitting the blade A being used as an ordinary straight blade razor.

Should the user desire to attach the safety device B, he closes theblade A and the lower end of the shank 18 of the razor A and the shankof the safety device B will engage with the distance piece 16 and beheld in the desired position, so that the laterally projecting pin 12will register with the enlarged end of the keyhole slot 20, whereuponthe finger grip 21 is engaged and the safety device B movedlongitudinally relatively to the blade A, so that the hooked end 22 willthus be brought into engagement with the end of the blade A.

he undercut edges of the pin 12 will have engaged with the keyhole slot20, thus preventing any tendency of lateral movement of the safetydevice B. The blade A may now be rotated outwardly from the handle 10,and in so doing the safety attachment B will also be rotated it is nowheld in frictional engagement with the blade A.

The razor now of the safety type may be used with freedom, and when theuser has shaved the safety device B may be detached from the blade A, topermit of the cleaning of the blade and safety device, which will thenbe located between the side members 'of the handle 10 and movedlongitudinally so that the hooked end 22 will engage with the projectinglip 15, "of the distance piece 13 and hold the safety device closed.

The blade A can then be rotated individually and it will be evident thatthe blade may behoned and stropped in the same manner as the ordinarystraight blade.

After the razor has been in use sometime it may happen that due to wear,grinding, etc, the blade A will become worn, and it will be necessary tomake adjustment of the safety device B relatively to the blade A,

and to this end 1 have provided the safety device B with a pair ofU-shape'd slots 2a in the shank 18. One of the U shap'edslots 24 isengaged with the hinge pin 11, and the other may be engaged with theprojectingpin 12. V

Itwill be evident, that if 'th'e hinge pin 11 and projecting pin 12engage with the upper parallel arm of the horizontally disposed U-shapedslots, then the safety device B will overhang the cutting edge of therazor A to a certain extent.

After the blade has become worn, the hinge pin 11 and the pin 12 may been gaged with the lower parallel arm of the horizontally disposed Ushaped slots 21 thereby adjusting the safety device B relatively to theblade A, so that the serrated edge of the safety device will overhangthe cutting edge of the blade to the desired e.\'- tent.

In Figs. 3 and 4: a slight modification of the safety device is shownand connects in forming the device in two portions, 25 and 26, theportion 25 having a slot 27 and a projecting tongue 28, the former ofwhich is engaged by the projecting tongue 29 on the shank 25, while thetongue 28 is designed to engage with the elongated orifice having aserrated side wall 30. By providing the serrations in the orifice 30 thetongue 28 may be engaged with any of the serrations to alter the heightof the portion 26 relatively to the portion 25.

In Figs. 7 and 8 the safety device B differs from that shown in Fig. 1by eliminating the finger grip '21 and offsetting, the end 33 of theshank of the safety device, a lever 31 is hinged on the pin 11, the saidlever having a projecting arm 32 which is adapted to engage the front orrear face of the offset end portions 33.

When the device B is adapted to engage with the blade A then the arm 32engages with the front of the offset end 33 of the shank 18. y

The device B is disengaged from the blade A by moving the devicelongitudinally, and the arm 32 of the lever 31 is engaged with the outerface of the offset end 33 so holding the hook end 20 of the safetydevice B dis engaged from the end of the blade A.

The blade A can be used individually or in conjunction with the safetydevice and the blade can be cleaned, honed, stropped, etc, with care andthe safety device readily adjusted to the blade A. i

As many changes could be made in the above construction and many widelydifferent embodiments of my invention within the scope of the claims,constructed without departing from the spirit or scope thereof, it isintended that all matter contained in the accompanying specification anddrawings shall be interpreted as illustrative and not in a limitingsense.

Vhat I claim as my invention is:

1. The combination with a-straight blade razor, of a safety devicepivotally attached to the blade, and capable of being movedlongitudinally relatively thereto, and means for securing the safetydevice to the blade.

2. The combination with a straight blade razor, of a retaining meanscarried by a handle of the razor, a safety device pivoted to the bladeand designed when not in use to engage the retaining means, the saidsafety device being movable longitudinally of the blade, and means forsecuring the safety device to the blade.

3. The combination with a straight blade razor, of a safety devicehaving a serrated guard and shank pivotally attached. to the razor,lateral displaceable spring members integral with the shank and coactingwith the razor blade, and hook means on the safety device designed toengage or disengage with the straight blade of the razor on longitudinalmovement of the safety device.

4. The combination with a straight blade razor, of a safety devicehaving a serrated guard and a shank provided with a U- shaped orificetherein, a projection carried by the safety razor blade coacting withthe U-shaped orifice, and means for pivotally at taching the safetydevice to the razor blade:

5. The combination with a straight blade ing the point of the safetydevice to the point of the razor blade.

6. The combination with a straight blade razor of a safety devicecapable of combined longitudinal movement and transverse movement, thesafety device on longitudinal movement interlocking with the straightblade razor.

In witness whereof I have hereunto set my hand.

ANDREW MCANULTY.
